Factual error: As Stef is stepping down the fireplace, you can see that her Nike swooshes are drawn on her shoes. Nike never made shoes like that. Converse made them for a couple years in the 80s. (00:46:00)
Revealing mistake: When the floor crumbles from under Mouth we see a shot looking up from the pit to him leaning back trying to keep his balance. If you look closely you can see him kneeling on the ground helping him to lean back further.
Continuity mistake: When Stef explains to the others why they shouldn't take the coins of the well, Mouth is standing next to Data silently counting the money in his hands. In the next shot of Mouth explaining how his wish didn't come true, he is now standing farther away from Data. (01:01:20)
Other mistake: When Mouth is examining the coins in the well scene, if you look closely he keeps on dropping the same coin in his hand then picking it up to examine it again. Also note that the penny he first examines is practically the size of a half dollar coin. (01:00:35)
Continuity mistake: When Mikey punches through the boards leading into the room with the treasure, you can see light coming through the opening. This could not be possible since there's a door on top of the opening that should block out any light. (01:27:25)
Continuity mistake: When Mouth returns downstairs with Rosalita and Mikey's mom, Chunk already has the statue he broke turned away so no one will see, in the next shot he turns the statue away from everyone's view. (00:12:25)
Continuity mistake: At the country club, when Troy is going into the bathroom stall we can see the back and front cover of the 'Guns & Ammo' magazine he is looking at, but when he hears the noise and looks around he is holding a different issue of the 'Guns & Ammo' magazine. (00:51:00)
Revealing mistake: When Francis Fratelli is trying to pick up the gun as the Goonies are escaping from the organ, you can see the rocks shaking each time he drops the gun on the ground.
Other mistake: In the Summer Place scene, after Mama Fratelli sets down four glasses of "colored" water for the boys to drink. The next camera angle shows Mouth wiggling his glass in the air as he retorts, "We're supposed to drink this?", Mama snaps back, "It's wet isn't it? Drink it." If you look closely for 2 seconds you can see Corey Feldman is trying very hard to not smirk at this line, while struggling to stay in-character, as Mikey and Data say their next lines.
Factual error: The Goonies are from Astoria, but they ride their bikes to Cannon Beach; this is where the Lighthouse Lounge is, a distance of over 30 miles. When they descend in the tunnels below the lounge, they supposedly go under Astoria Country Club and Moss Garden. This would be impossible.
Continuity mistake: When Brand takes Data's sister's bike, there is a horn affixed to the handlebar which disappears when Troy pulls up beside Brand in his car and then reappears when Troy starts speeding holding Brand's arm.
Continuity mistake: We see Mouth climb down into the fireplace passage after Brand and Andy. We then see a close-up of Stef's pink high-tops descend, being helped by Mouth (we see his rain slicker), who's already down there with Brand and Andy, who are visible in the background. It cuts to a close-up of Stef, with Data's white Nike high-tops climbing down after her. But the next close-up is of Mouth's feet (black Nikes) just coming down as Brand grabs his ankle and says, "Come on!" Impossible since Mouth was already down there. (00:45:20)
Continuity mistake: When the boys reach the attic Brand fixes the flickering lightbulb. Then they show a shot of Mikey and Mouth and you see Brand fixing the flickering lightbulb again in the background. (00:14:04)
Continuity mistake: When the Fratellis are trying to get information from Chunk, the amount of juice in the blender changes between shots.
Other mistake: When Chunk is reading the caption under Chester Copperpot's picture he says, "I have the key to One-Eyed Willy." The caption, however, only says that Chester has a key, but never says to what.
Factual error: When the Fratellis are getting away from the police at the beginning of the movie they go to the beach to blend in with the other 4x4s. Mama Fratelli tells Francis to put their Jeep into 4 wheel drive but you can see him put it into 4 wheel low. It's impossible to drive as fast as they did on the beach in 4 wheel low.
Revealing mistake: After Chunk smashes the statue and Mikey tries to put the penis back on it, we can see the statue is fake and is just made of rubber. When Mikey pushes the penis against the statue, the statue bends inwards slightly. (00:09:25)
Continuity mistake: On the beach, when Mr. and Mrs. Walsh leave the van and then rush to Mikey and Brand, Mikey's knit hat is pulled down low over his ears, but next shot it is folded up above his ears, though he never touches it. (01:41:55)
Continuity mistake: When Mouth first shows up at the Walsh's, in the wideshot as Brand is stretching the chest expander, Brand's left leg is crossed over his right, but in the close-up it's right over left. (00:06:30)
Continuity mistake: On the beach, when Mikey tells his father, "We had our hand on the future, but we blew itÂ…," in the close-up the brown blanket is only on Mikey's left shoulder, but in the previous and following shots the blanket is snugly around both shoulders. (01:45:25)
Chosen answer: Well, his ship is hidden in America where the people spoke english, so perhaps it was done for the benefit of those who were most likely to find the map. Must have been his idea of a joke.Actually though, I'm betting it was the result of the filmmakers not thinking that through.
